Just a night before the start of the 2022 World Cup in Qatar, Portuguese legend Cristiano Ronaldo took to his social media account to share his first-ever partnership deal with his eternal rival, Lionel Messi.

The duo, who have shared the great stage of football for many years, portraying themselves as the best-ever players in the game, have had several deals that have seen them earn a fortune from various companies.
